Yes, well. I wrote the "work order," but I'm neither the programmer nor the developer. It doesn't work on all mosquitoes, either. You got lucky.Your miracle MosquitoKiller program
If you've been using the wrong pattern, it's possible the microphone has been partially aimed at the noise source rather than trying to ignore it. That might go a long way to solving the environment noise problem. That's why the cardioid pattern is recommended for podcasters.I have been using the wrong one.
The British version of that is "kidney" pattern for obvious reasons. You may find your vocal tone may shift a bit when you change patterns.
That pattern also exhibits Proximity Effect. Tone changes with distance, being particularly striking the last three or four inches. I can turn myself into a ballsy broadcast presenter just by leaning forward. It's an old story, but I once briefly played two different people by doing that and changing vocal style.
You should not change anything if you're in the middle of a book and you're supposed to be one person.
